TheA-scaling of the multiplicity distributions ofπ ′,K − and $$\bar P$$ interactions with nuclei at 40 GeV/c

Abstract

The multiplicity distributions of charged particles produced from π−,K− and\(\bar p\) interactions with the nuclei Li, C, S, Cu, CsI, Pb at 40 GeV/c were studied. It was found that the linear relationD=a〈n〉+b is satisfied for the distributions of different kinds of secondary particles including knocked out protons. Consequently, the use of the scaling variablez′=(an+b)/(a〈n〉+b) ensures the scaling of the distributions with respect to the mass numberA at least up to the second moment.
